The selective adsorption and flotation separation of
Spodumene and feldspar have little difference in flotability due to their similar crystal chemistry properties. Fe-octyl hydroxamic acid (OHA) (iron complexes of octyl hydroxamic acid) demonstrates excellent selectivity but restricted collecting performance in spodumene flotation.In this work, we added sodium dodecyl sulfate …

11.27 Feldspar Processing
A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid ...

Feldspar Beneficiation & Flotation Process
The problem in feldspar flotation is to recover slime free granular products, all minus 20 mesh, usually with not over 10% finer than 200 mesh. Flotation under these conditions is critical and pulps are abrasive as well as corrosive. Action of the feldspar pulp must be counteracted by proper selection of equipment to withstand these conditions.

Abstract. Feldspar and quartz are similar in composition and structure, and hence, they exhibit low flotation separation efficiency in acid or alkaline conditions and while using the traditional reagents scheme. In this study, hydroxypropyl starch (HPS) was introduced as a novel depressant in the flotation separation of quartz from feldspar.
